# **Open Network Diagram**
|
||
|
||
|
||
|
||
|
||
|
||
|
||
|
||
**A declarative, self-hosted tool for visualising and managing home lab & network architecture diagrams.**
|
||
|
||
---
|
||
|
||
## **📝 About**
|
||
|
||
**Open Network Diagram** is an **open-source, self-hosted tool** for creating **interactive network and infrastructure diagrams** using a **declarative JSON format**.
|
||
|
||
✅ **Fully self-hostable via Docker**
|
||
✅ **Docker-first deployment target** (Netlify optional for demo hosting)
|
||
✅ **Interactive network visualisation**
|
||
✅ **Simple file-based configuration**
|
||
✅ **Lightweight Svelte**
|
||
|
||
Use it to **document your home lab, office network, or cloud infrastructure** with an easy-to-use web interface.
|
||

|
||
|
||
## **🚀 Quick Start (For Users)**
|
||
|
||
### **1️⃣ Create Your Runtime Data File**
|
||
|
||
Copy the template and edit your own network data:
|
||
|
||
```bash
|
||
cp data/network.json.example data/network.json
|
||
```
|
||
|
||
### **2️⃣ Run Open Network Diagram via Docker**
|
||
|
||
From this repo:
|
||
|
||
```bash
|
||
docker compose up --build
|
||
```
|
||
|
||
Or pull and run directly:
|
||
|
||
```bash
|
||
docker run -d -p 8080:80 -v "$(pwd)/data:/usr/share/nginx/html/data:ro" jcreek23/open-network-diagram
|
||
```
|
||
|
||
- **`-p 8080:80`** → Maps the app to `http://localhost:8080`
|
||
- **`-v .../data:/usr/share/nginx/html/data:ro`** → Uses your local `data/network.json`
|
||
|
||
### **3️⃣ Open the Web UI**
|
||
|
||
Visit **`http://localhost:8080`** to view your network diagram.
|
||
|
||
### **4️⃣ Modify Your Network (JSON-Based)**
|
||
|
||
- Docker runtime reads **`/data/network.json`** from the mounted volume.
|
||
- In this repo, your editable file is **`data/network.json`** (gitignored).
|
||
- Netlify demo builds use committed sample data at **`static/data/network.json`**.
|
||
- After editing JSON, click **Reload Default JSON** in the UI.
|

## **📦 Docker Build & Deployment**
|
||
|
||
### **Build the Docker Image Locally**
|
||
|
||
```bash
|
||
docker build -t open-network-diagram .
|
||
```
|
||
|
||
### **Run Locally**
|
||
|
||
```bash
|
||
docker run --rm -p 8080:80 -v "$(pwd)/data:/usr/share/nginx/html/data:ro" open-network-diagram
|
||
```
|
||
|
||
### **CI/CD (GitHub Actions + Netlify)**
|
||
|
||
- GitHub Actions workflow (`.github/workflows/docker.yml`) builds Docker on PRs.
|
||
- Pushes to `main` publish Docker images to **Docker Hub** (`jcreek23/open-network-diagram`).
|
||
- Netlify uses its own CI/CD pipeline with `netlify.toml` (`pnpm run build:netlify`).

## **📝 JSON Network Configuration Example**
|
||
|
||
Define your network using **`network.json`**:
|
||
|
||
```json
|
||
{
|
||
"machines": [
|
||
{
|
||
"machineName": "ProxRouter",
|
||
"ipAddress": "10.0.0.3",
|
||
"role": "Hypervisor",
|
||
"operatingSystem": "Proxmox",
|
||
"software": {
|
||
"vms": [{ "name": "OpnSense", "role": "Router", "ipAddress": "10.0.0.4" }]
|
||
},
|
||
"hardware": {
|
||
"cpu": "Intel N100",
|
||
"ram": "8GB",
|
||
"networkPorts": 4
|
||
}
|
||
}
|
||
],
|
||
"devices": [{ "name": "Switch", "ipAddress": "10.0.0.2", "type": "Nintendo Switch" }]
|
||
}
|
||
```
